Spring Cloud Gateway路由配置的时候,要负载均衡的服务名称不能写"_" 下划线

 

原有的错误配置:

    gateway:
      routes:
        - id: qq_route
          uri: http://localhost:8000/
          predicates:
            - Query=url,index
        - id: manage-web
          uri: lb://manage_web
          predicates:
            - Path=/manage_web/** # 匹配的规则
          filters:
            - StripPrefix=1

修改后的配置:

    gateway:
      routes:
        - id: qq_route
          uri: http://localhost:8000/
          predicates:
            - Query=url,index
        - id: manage-web
          uri: lb://manage-web
          predicates:
            - Path=/manage-web/** # 匹配的规则
          filters:
            - StripPrefix=1

同时要将你负载均衡的服务名称修改为manage-web,不再是manage_web。要不然还会报错
